Answer 1

Answer:

Acceleration = -1.67 m/s

Explanation:

Given :

Speed = 60 km/hr = 60 * (5/18) = 300/18 m/s

Time = 10 sec

Here the brakes are applied. So it is in rest now. (V = 0)

Apply the formula :

a = (v - u)/t

⇒ a = (0 - 300/18)/10

⇒ 10a = -300/18

⇒ a = -5/3

⇒ a = -1.67 m/s

Therefore,

Acceleration = -1.67 m/s
